Figure 1. Expression of miR-93 in human breast carcinoma specimens. (A) RNAs were isolated from paraffin blocks of human breast carcinoma specimens and the benign breast tissues, followed by real-time PCR analysis of miR-93 levels. The breast carcinoma tissues expressed significantly higher levels of miR-93 than the benign tissues. (B) RNAs were isolated from paraffin blocks of human breast carcinoma specimens with lymph-positive (metastasis) and the benign breast tissues followed by analysis of miR-93 levels. The tumor tissues expressed significantly higher levels of miR-93.
